Australian company Electric Vehicle Systems and Technology (EVS&T) has developed a breakthrough technology with its patented ultra-low voltage (ULV) electric drive system.

At voltages as low as three, the equivalent power of an internal combustion engine can be electrically generated to drive light and heavy mobile mining machinery. The company has installed its drive system in a Toyota Landcruiser to great effect and could be applied to mining machinery very soon.

EVS&T spokesman Michael Byford says the safety implications alone of its patented ultra-low-voltage electric drive system are enormous.

"It removes the electrocution hazard for operators, maintenance personnel and emergency crews in the event of an accident," he says.

"The need for training personnel to work with high voltage can be removed."

In the mining industry the case for electric-powered mobile equipment is compelling. Electric drive systems have the potential to reduce ventilation costs, eliminate health concerns over DPM, allow deeper or more productive mines and add a great advantage to a mine’s social license to operate.

Machinery total cost of ownership will decrease because of less maintenance required by electric drive systems and the reduced running costs achieved by utilising electricity over fossil fuels. Such reduction favourably impacts a mine’s operating costs.

EVS&T’s ultra-low voltage solution eliminates the need for high voltages in the region of 340 to 1,000 volts which are presently the only way to power electric mining machinery.

These voltages, which carry significant safety risks and require stringent guidelines and work practises, dedicated charging facilities, and properly trained operators and maintenance personnel, can be removed from the risk assessment.
